iRehearse is a music phrase trainer designed to help musicians learn, practice and transcribe tracks. It features independent control of pitch and tempo, allowing you to slow down a song without changing the pitch, loop a section of a track until you get it right, and change the pitch of a song to match the tuning of your instrument.

Whether you play guitar, bass, drums, piano, trumpet, sax or any other instrument you care to mention, iRehearse can help you learn and play those tricky songs.

Control the tempo (speed) of your track without adjusting the pitch. This means you can slow down a particular section of a song (the big solo for example) and hear each note more clearly. And as the pitch has not changed, you can still play along.

iRehearse allows you to change tuning by semi-tones up and down two whole octaves (12 semi-tones = one octave). It also allows fine tuning using cents (100 cents = one semi-tone).

iRehearse allows you to mark a specific region of a track and play just that section. You can also select if you wish to play this section just once or repeat it over and over again. Of course all of your pitch and tempo settings will effect this loop so you can slow down the section to really hear what's going on. Ideal for practising that long drum fill or guitar solo.

The Playlist allows you to setup a list of tracks that iRehearse will play one after another, ideal if you have a whole gigs' worth of music to rehearse. Each track within the list has its own individual player settings that are automatically loaded as the track begins to play. This means that the first track can have a pitch shift of one semi-tone, have boosted treble and be at a high volume, while the second track in the list can have normal EQ and pitch settings, but have a tempo increase of 10%.

NOTE: iRehearse is an audio player and not an audio editor/exporter. It is simply designed to help musicians practice and as such does not include any audio export options. Saving loops simply saves the player's status for a particular track so you can have your favourite settings for each songs quickly and easily. It does not export any audio data in any format.

Good, but some flaws.

This is a cool app in some ways - the ability to slow down, change pitch and basically equalise is great. The playlist function is also pretty cool.

Its major flaw though is in the loop function. It doesnt repeat the exact same loop over and over, and often glitches by running a few milliseconds over or under the intended loop, or pausing.

Dont let this deter you though from its other functions. Its still a good app - i would just like to see the loop function fixed so it is more reliable.
